Aggrastat to Zocor (AtoZ) - the Use of Two Approved Drugs to Treat Patients Who Have Experienced Chest Pain or a Heart Attack (0733-180)
A Multicenter, Randomized, Controlled, Double-Blind Trial to Investigate the Clinical Efficacy and Tolerability of Early Treatment With Simvastatin 40 mg Daily for 30 Days, Followed by Simvastatin 80 mg Daily Thereafter in Tirofiban-Treated Acute Coronary Syndrome Patients Who Have Been Randomized to Receive Enoxaparin or Unfractionated Heparin in Conjunction With Aspirin
A-Phase: Evaluating patients with chest pain who are receiving approved drugs, to estimate the effectiveness of one type of blood thinner as compared to another type of blood thinner.
Z-Phase: To evaluate early treatment of patients with long term chest pain (using an approved drug for 30 days, followed by an increased dose of the drug) as compared to patients (treated with diet and 4 months placebo followed by diet and approved drug) in patients who have experienced acute chest pain or heart attack.
